<p>Array of moves to be performed by the user in the current defragmentation pass. </p>
<p>Pointer to an array of <code>MoveCount</code> elements, owned by D3D12MA, created in <a class="el" href="class_d3_d12_m_a_1_1_defragmentation_context.html#a1606c015d02edc094bb246986159d592" title="Starts single defragmentation pass.">DefragmentationContext::BeginPass()</a>, destroyed in <a class="el" href="class_d3_d12_m_a_1_1_defragmentation_context.html#aad502ba70d6dadaeee37703fd8bf90ae" title="Ends single defragmentation pass.">DefragmentationContext::EndPass()</a>.</p>
<p>For each element, you should:</p>
<ol type="1">
<li>Create a new resource in the place pointed by <code>pMoves[i].pDstTmpAllocation-&gt;GetHeap()</code> + <code>pMoves[i].pDstTmpAllocation-&gt;GetOffset()</code>.</li>
<li>Store new resource in <code>pMoves[i].pDstTmpAllocation</code> by using <a class="el" href="class_d3_d12_m_a_1_1_allocation.html#a414a088c22bae0f29b1038f5f9346d14" title="Releases the resource currently pointed by the allocation (if any), sets it to new one,...">Allocation::SetResource()</a>. It will later replace old resource from <code>pMoves[i].pSrcAllocation</code>.</li>
<li>Copy data from the <code>pMoves[i].pSrcAllocation</code> e.g. using <code>D3D12GraphicsCommandList::CopyResource</code>.</li>
<li>Make sure these commands finished executing on the GPU.</li>
</ol>
<p>Only then you can finish defragmentation pass by calling <a class="el" href="class_d3_d12_m_a_1_1_defragmentation_context.html#aad502ba70d6dadaeee37703fd8bf90ae" title="Ends single defragmentation pass.">DefragmentationContext::EndPass()</a>. After this call, the allocation will point to the new place in memory.</p>
<p>Alternatively, if you cannot move specific allocation, you can set <a class="el" href="struct_d3_d12_m_a_1_1_d_e_f_r_a_g_m_e_n_t_a_t_i_o_n___m_o_v_e.html#a5ba8d6894267ae59df4efb9972af5d81" title="Operation to be performed on the allocation by DefragmentationContext::EndPass().

New place reserved at pDstTmpAllocation will be fre...">D3D12MA::DEFRAGMENTATION_MOVE_OPERATION_IGNORE</a>.</p>
<p>Alternatively, if you decide you want to completely remove the allocation, set <a class="el" href="struct_d3_d12_m_a_1_1_d_e_f_r_a_g_m_e_n_t_a_t_i_o_n___m_o_v_e.html#a5ba8d6894267ae59df4efb9972af5d81" title="Operation to be performed on the allocation by DefragmentationContext::EndPass().
